(01. 229-92.8)

The present invention relates to paper blanks for forming articles for despatch through the post, in the nature of postcards, and it has for its primary object to provide an article which,

after despatch and receipt by the recipient, can,

in a simple way, single sheet of paper.

be restored to the form of a fold at which the two by tearing, one of said sheet and the other p portions can be separated portions serving as a copy ortion being divided along the centre of its height by a folding line by which the said portion is adapted to carry the divided into two sections, one

address and the other to carry the writing forming the desired communication, the said other portion being adapted to be folded along said folding line, whereupon the upper and the lower edges thereof can be fastened together to form the completed article for despatch.

The attached drawing shows the paper blank in accordance with manner in which it is Fig. 1 shows the complete shows in front view,

which is folded double,

Fig. 2 the blank Fig. 3 shows in side view sheet as shown in Fig.

the postcard formed from the Fig. 4 shows blank Fig. 5 shows As shown in Fig. prises two portions at the centre by a the two portions I and 2 can tearing. The folding advantageously be formed by an of weakening formed like elements.

The sheet I can be sheet in front view,

the card in side view.

1, the paper sheet blank cornand 2 which are connected folding line 3 along which the invention, indicating the used and in which: blank,

the sheet forming the double folded and be separated by line can, for this purpose, impressed line by a series of short dashfolded around the folding line 3 at the rear of the sheet 2 as shown in Figs. 2 and 3 and it is adapted to serve as a copy sheet.

The sheet 2, that is the front sheet, is, at the centre of its height, provided with a folding line 4. By means of this f is divided into an address section 5 and section 6 adapted to olding line, the front sheet another bear the writing forming the desired communication.

After writing out the address and the desired communication and a copy thereof taken on the sheet I, the latter sheet is separated along the fold 3.

Then the sheet 2 is folded on itself along the folding line 4 as indicated in Figs. 4 and 5.

Finally, the edges 1 of the sheet together are secured geously by means of a in the known way, tached are drawn 2 thus brought to one another, advantasealing machine in which,

the two sheet edges to be atbetween two polished rollers running in the opposite directions. In this way a postcard is obtained of the ordinary dimensions.

If the postcard is to be opened out after receipt, then the edges 1 are separated from each other, for example by drawing them between the 5 nails of the thumb and one finger or by tearing or pulling apart, whereby the said two edges are separated and an ordinary sheet of postal paper produced.

The paper blank according to the invention has various advantages, which may be summarized as follows:

The postcard formed is constituted by ordinary paper and is therefore cheap. The copy sheet is fastened to the portion of the sheet which forms the postcard and is therefore always ready for use. The copy is clearer than in the case of a postcard formed of card since the sheet on which the writing is performed is thinner. The copy sheet is stronger and larger than those 2 which are used with ordinary postcards and they can be therefore more easily and satisfactorily held in a letter file. The surfaces for the address and for the text lie in a single plane whereby reversal in the typewriter is made unnecessary.

The postcard to be despatched can be secured by perforation with teeth or by the impression of a name. The recipient of the postcard can easily open by pulling the fastening between the nails of the thumb and one finger, whereby a sheet of normal size and thickness is obtained which can be placed in a letter file. The recipient of the card therefore does not have to insert a comparatively stiff card into his letter file, which would hinder the turning over of the sheets.

The half letter or memorandum thus becomes unnecessary since the paper blank in accordance with the invention can be used in an envelope. For this reason less types of letter paper are necessary in an ofiice.

The paper blank in accordance with the invention can naturally also be used for those cards bearing printed matter, of which copies must be taken.

What I claim is:

A paper blank for forming a postcard embodying an integral part adapted to serve as a copy sheet, the remainder of the blank after removal of said part by tearing being foldable along a centre line to form the card for despatch by post, only the edges of said folded blank being secured together, permitting the folded blank to be fastened together to form a card suitable for postal conveyance, the edges being adapted to be subsequently cut away or separated to permit the folded blank to be restored to its original sheet form.
